FAQ_istock_250w.jpg

What market opportunity does HomePlug technology address?
HomePlug products leverage the ubiquity of power outlets and electrical wiring to enable scores of connected home applications. HomePlug networking products have been shipping throughout the world.

What are the benefits of using power outlets to connect devices found in the home?
HomePlug networks are far easier to install than pulling the dedicated network cable needed for purely Ethernet-based networks. HomePlug networks can also be used to extend wireless coverage by plugging HomePlug + Wi-Fi extenders into the powerline network in areas of poor Wi-Fi connectivity. HomePlug AV and AV2 address the need to distribute entertainment content, such as Ultra HDTV, throughout a home. Power outlets are the most pervasive home wiring medium. Power outlet connectivity is available worldwide, affording the use of multiple outlets in every room at a lower cost per connection point. HomePlug technology leverages existing power outlets to provide both increased performance and coverage. Additionally, the convenience of connecting any device through a power outlet enables exciting new products covering entertainment, information access, telephony services, and smart home devices.

What are the challenges of using power outlets to connect devices in the home?
Past challenges of using power outlets to connect devices in the home included a lack of industry specifications, multiple sources of electric noise, and difficulty passing through phases in the home. HomePlug technology has overcome these challenges by creating specifications with advanced, optimized algorithms that are realized in semiconductor technology.

 - Problem Solved: Lack of standards
 - Problem Solved: Multiple sources of noise
 - Problem Solved: Connecting through different electrical phases

Is HomePlug powerline technology compatible with other home networking technologies (including phone line, wireless and structured wiring)?
HomePlug technology does not interfere with other non-powerline networking choices, and, in fact, can work together with them. For wireless technologies, HomePlug Wi-Fi extenders bridge wireless and powerline technologies, allowing you to connect all your mobile devices. Homes with Ethernet Category 5 wiring will most likely have rooms or walls without available connectivity. Because of the ubiquity of power outlets, consumers are guaranteed to have a power outlet available for non-mobile devices.

What is nVoy®, and how does it relate to HomePlug?
The nVoy program provides the industry with product certification and marketing for interoperable solutions implementing the IEEE 1905.1 hybrid home networking standard. Products with nVoy Certification will support and foster harmony between wired and wireless home networking technologies including HomePlug, Wi-Fi, MoCA and Ethernet. The nVoy program is being managed by Broadband Forum.

How are the HomePlug technology specifications made available?
The specifications are available for download from this page.

What Quality of Service (QoS) support does HomePlug AV provide for emerging AV and IP applications?
HomePlug AV provides advanced QoS functions and features geared towards meeting the latency and jitter requirements of all emerging AV and IP applications.

Does HomePlug AV address the "hidden node" issue?
Yes, the "hidden node" issue is a critical one seen by many LAN technologies, including Wi-Fi. HomePlug AV addresses this by using sophisticated network management capabilities, including a proxy networking function.

Does HomePlug AV address security?
HomePlug AV uses 128-bit AES security.

Are HomePlug AV/AV2 and HomePlug Green PHY™ devices interoperable?
Yes, HomePlug AV/AV2 and HomePlug Green PHY devices are interoperable.
 
Which frequency range are HomePlug AV and AV2 using?
HomePlug AV uses frequencies in the range of two to 28 MHz. The IEEE 1901 standard extends this range optionally to 50 Mhz. HomePlug AV2 utilizes frequencies in the range of 30 to 86 MHz to increase throughput.

What underlying technologies does HomePlug AV employ?
HomePlug AV uses an OFDM PHY with advanced FEC, channel estimation and adaptation. The MAC incorporates both scheduled access (TDMA) with QoS guarantees and contention access (CSMA), with reliable delivery through fast ARQ. HomePlug AV supports TDMA and FDMA for purposes of Broadband over Powerline (BPL) co-existence. The HomePlug AV protocol stack supports a variety of upper layer protocols native to HomePlug AV, 802.3, IP and UPNP.

Are HomePlug technologies global?
Absolutely. HomePlug specifications work on power lines regardless of location, subject to local government regulations.

Does HomePlug AV address Access BPL co-existence?
Yes. “Access BPL” is the term used for using powerline communications outside and to-the-home. HomePlug technology supports coexistence and interoperability between in-home and Access BPL. Interoperability will allow devices in both the in-the-home and BPL domains to connect and interact seamlessly.

HomePlug AV has a mechanism to detect the existence of neighbor networks, which includes Access BPL users. This mechanism is required so that in-home-only HomePlug AV users in homes and apartments that are sharing the same physical wire (off of a common transformer) do not interfere with each other - independent of whether Access BPL exists on the line or not. In other words, the need for bandwidth sharing exists inherently within HomePlug AV itself, and the bandwidth management solutions needed for In-home HomePlug AV applications can easily be extended to HomePlug Access BPL.

What are HomePlug AV2's features and capabilities?
HomePlug AV2 was designed to support the high-bandwidth and low-latency demands of several simultaneous streams of 4K Ultra HDTV and VoIP, made concurrently available in over 100 percent of power outlets in a home.

What QoS support does HomePlug AV2 provide for emerging AV and IP applications?
HomePlug AV2 provides advanced QoS functions and features geared towards meeting the latency and jitter requirements of all emerging AV and IP applications. Extensive field trials have been conducted to determine the optimal technology path for AV2. For more information, click here.
